Any curve that is not symmetrical is referred to as skewed or asymmetrical. A curve may be positively skewed, which means that the largest portion of data is below the mean. A curve can also be negatively skewed, which means that the largest portion of data is above the mean. In a skewed distribution, the mean, median, and mode are not equal. In a positively skewed distribution, the mean is greater than the median, which is greater than the mode. In a negatively skewed distribution, the mean is less than the median, which is less than the mode.
